Some of the health benefits of drinking carrot juice include a reduced risk of cardiovascular disease, lung cancer, colorectal cancer, prostate cancer and leukemia. As part of a diet high in antioxidants, carrot juice can also help reduce the overall risk of cancer. Other possible health effects of carrot juice include improved immune functioning and better blood sugar regulation.
The beta carotene in carrot juice is what gives the juice its orange color. The body converts beta carotene to vitamin A, so the juice also helps prevent vitamin A deficiencies. Some people who drink a lot of carrot juice develop an orange tint to their skin because of the high levels of beta carotene, but it is not harmful.
While carrots are often touted as being good for vision, there is no evidence that consuming carrots or carrot juice can improve eyesight in people with normal vision. Ingesting beta carotene or vitamin A only improves the vision of people who have experienced vision problems as a side effect of a vitamin A deficiency.
In addition to having high levels of beta carotene, carrot juice also contains calcium, iron, vitamin C, vitamin K, folate and potassium, making it a healthy drink that provides essential nutrients to the body. Carrots that come in unusual colors, such as red and purple, may also contain additional beneficial antioxidants, such as lycopene or anthocyanin.
